Abstract: A coated inorganic powder composition for the treatment of plants comprises an inert inorganic powder, an active powder and a bonding ingredient for improving the adhesion of the composition to plant surfaces.  The bonding ingredient comprises a water-insoluble cationic amphiphilic compound present in an amount sufficient to coat each powder particle of at least the inert constituent, or at least the active constituent if the latter is inorganic, but insufficient for the composition to lose the character of a powder.  The composition may comprise a major proportion of clay, kaolin or talc, and a minor proportion of the "active" ingredient, e.g. copper oxychlorides, sulphate and other copper salts (as in fungicides), iron, zinc and manganese carbonates, or synthetic organic compounds such as organo-halogen base insecticides and organo-phosphor base pesticides. Suitable cationic amphiphilic compounds are: aliphatic diamine derivatives such as stearyl-diamine distearate, dioleate, aminoleyldiaminedioleate, linoleyl-diamine dilaurate, palmityl-diamine dipalmitate; aliphatic alcohol acids, e.g. ricinoleic acid and/or oxide acids; derivatives of aromatic acids and amine or polyamines, e.g. stearylamine naphthenate; quaternary ammonium salts of imidazolines, e.g. alkylimidazoline monoleate, amides derived from amino-alcohols, e.g. alcoylamine monoalkyl ester. A wetting agent comprising non-ionic, water-soluble compounds, e.g. fatty acid polyethoxy-esters such as polyethylene-glycol monoleate, alkyl-phenol polyethoxyesters such as polyoxyethylene nonyl-phenol, and cationic, water-soluble compounds, e.g. aliphatic amine derivatives such as laurylamine acetate, and quaternary alkylamine acetates may be added. The cationic amphiphilic compounds and wetting agents may be dissolved in a suitable solvent, e.g. trichlorethylene, the powder composition added and mixed uniformly and the solvent evaporated (and recovered).  Alternatively the solution and the powder may be mixed by spraying in a vacuum enclosure and the solvent recovered by a refrigeration condenser, or only the inorganic constituents may be coated.ALSO:Inorganic powder composition for the treatment of plants comprises an active powder constituent, an inert powder constituent, and a bonding ingredient for improving the adhesion of the composition to plant surfaces.  The bonding ingredient comprises a cationic amphiphilic compound which is at least substantially insoluble in water and is present in an amount sufficient to coat each powder particle of at least the inert constituent, or at least the active constituent if the latter is inorganic, but not great enough to provide an excess of free bonding ingredient in the composition, so that the composition retains the character of a powder.  The powder may be any agricultural composition.  The treating powder is said to generally comprise a major proportion of an inorganic filler of a variable and complex composition including such minerals as clays, kaolin, talc, calcium and potassium salts, and a minor proportion of the "active" ingredient which may include metallic salts e.g. copper oxychlorides, sulphate and other copper salts (as in fungicides) iron, zinc and manganese carbonates, or synthetic organic compounds such as organo-halogen base insecticides and organo-phosphor base pesticides. Suitable cation amphiphilic compounds are: aliphatic diamine derivatives such as stearyl-diamine distearate, dioleate, aminoleyldiaminedioleate, linoleyl-diamine dilaurate, palmityl-diamine dipalmitate, aliphatic alcohol acids e.g. ricinoleic acid and/or oxide acids; derivatives of aromatic acids and amine or polyamines e.g. stearylamine naphthenate; quaternary ammonium salts of imidazolines e.g. alkyl-imidazoline monoleate, amides derived from amino-alcohols e.g. alcoylamine monoalkyl ester.
